You and I both know this is complicated stuff, don't we?
There are other sources that could be used as well. Ground speed,
altitude and vertical speed are in theory available from the ins,
which is completely independent of the air data system. Such data
could be used for a sub level sanity check of the air data system.
If the adr disagree and drop out, there is a historical trending
relationship between ins ground speed and adr air speed, which will
be valid short term as degraded data. Whether this is used in the
330 is not known, but it doesn't seem to have been available in any
form to the crew or the stall warning functions.
For stall warning inhibition on the ground, ins data is arguably
a far more relevant source than anything else and wouldn't
require any wow detection ?...
